By two o'clock scarcely a man remained at the camp. Mr. Underwood and Darrell were among the last to leave. Two faithful servants of Mr. Underwood's had arrived an hour or so before, who were to act as watchmen during the shut-down. Having taken them around the camp and given them the necessary instructions, Mr. Underwood then gave them the keys of the various buildings, saying, as he took his departure,-- "There's grub enough in the boarding-house to last you two for some time, but whenever there's anything needed, let me know. Bring over some beds from the bunk-house and make yourselves comfortable." He climbed to a seat on one of the wagons, and, as they started, turned back to the watchmen for his parting admonition: "Keep an eye on things, boys! You're both good shots; if you catch anybody prowling 'round here, day or night, wing him, boys, wing him!" The teams then rattled noisily down the canyon road, Darrell, with Trix, bringing up the rear, feeling himself a sort of shuttlecock tossed to and fro by antagonistic forces in whose conflicts he personally had no part and no interest. However, he wasted no moments in useless regrets, but rode along in deep thought, planning for the uninterrupted pursuit of his studies amid the new and less favorable surroundings. Thus far he had met with unlooked-for success along the line of his researches and experiments, and each success but stimulated him to more diligent study. On their arrival at Ophir, Mr. Underwood gave directions to have the assaying outfit taken to the rooms in the rear of his own offices, after which he and Darrell, with the remaining teams, proceeded in the direction of The Pines. Trix, on finding herself headed for home, quickened her steps to such a brisk pace that on reaching the long driveway Darrell was considerably in advance of the others. He had no sooner emerged from the pines into the open, in full view of the house, than Duke came bounding down the driveway to meet him, with every possible demonstration of joyous welcome. His loud barking brought the ladies to the door just as Darrell, having quickly dismounted and sent Trix to the stables, was running up the broad stairs to the veranda, the collie close at his side. "Just look at Duke!" Kate Underwood exclaimed, shaking hands with Darrell; "and this is only the second time he has met you! You surely have won his heart, Mr. Darrell." "You are the only person outside of Katherine he has ever condescended to notice," said Mrs. Dean, with a smile. "I assure you I feel immensely flattered by his friendship," Darrell replied, caressing the collie; "the more so because I know it to be genuine." "He won't so much as look at me," Mrs. Dean added. "That is because you objected at first to having him here," said Kate; "he knows it, and he'll not forget it. But, Mr. Darrell, where is papa?"
